In the area between the south portal of the existing Giswil tunnel and the new Kaiserstuhl tunnel (separately already awarded as Lot 19), the road infrastructure will be expanded so that in future national and cantonal roads can be managed separately via two separate Trassees. The current Trassee of the Brünigstrasse runs over the existing Buochholz bridge, past the OWi-Land to the Lungerersee. The existing Buochholz bridge will be used for the national road after the opening of the Kaiserstuhl tunnel. For the cantonal road, a new road bridge will be built parallel to the existing bridge (separately already awarded as lot 20).
